Weights and Measurements

The millisievert gamma-radiation [mSv γ] is a derived unit of ionizing radiation dose in the International System of Units (SI) and is a measure of the effective biological damage of low levels of ionizing radiation on the human body caused by exposure to gamma (γ) radiation in thousandths of a sievert.

Scientifically, the weight of a body is the gravitational force acting on the body, and directed towards the center of gravity with magnitude of the force depending on the mass of the body.
